Hello. I realize in writing this I'm discussing two unsupported
branches of NetBSD, but
I'd like to understand how to tackle this problem in the general case.
the issue seems to be that the tools/compat library under sources for
NetBSD-9.99.77 won't
build under NetBSD version 10.99.12. Specifically, the issue has to do with
the fact some
macros defined in sys/endian.h under 10.99.12 are not recognized by the
tool/compat code under
9.99.77 causing the compiler to complain there are multiple definitions for the
same macros.
In looking at tools/compat/configure.ac, version 1.98 (9.99.77) versus 1.108
(10.99.12), I
don't see any differences obviously related to the endian macros. The error
snippet below
shows the problem. If anyone has any ideas on how to go about making this
issue go away, that
would be helpful. The src-9.99.77 tree was building fine up to the point where
I upgraded the
build host to 10.99.12.
-thanks
